Explanation: DNA microarrays are used to study interactions among genes in a genome.

Muscle cells contract because of contractile proteins.
<h2>
Answer:</h2>
This is basically because of lack of <u>mitochondria </u>in lower life forms.
<h2>
Explanation:</h2>
- Glycolysis is a Anaerobic(without oxygen) process in which glucose is breakdown in smaller forms without consuming oxygen.
- So glycolysis is the simplest sourse of energy production and hence it is commonly seen in both lower and higher organisms.
- However, immediately after finishing glycolysis, the cell will continue either aerobic or anaerobic respiration, this choice depends upon the presence of oxygen and mitochondria as the further process after glycolysis i.e kreb cycle(Citric acid cycle), electron transport chain (ETC) take place in mitochondria with the presence oxygen, and<u> lower organisms lack mitochondria</u> hence they cannot perform process after glycolysis.
Result: Smaller organisms obtain energy only by glycolysis.
